Have light / blinker issue: Head Lights Off: When left blinker on - right front blinker also blinks When Headlights On: Left Rear Turn Light Stuck On. Left Blinker does not work. Right Blinker works fine. Any Ideas? Changed headlight and all Turn Signal lights. Check Fuses - Nothing.

check the ground wires to the rear lights sometimes the head lights will provide backfeed ground when off but cannot when on this would explain the rapid flash

Your right rear turn signal bulb is blown.Replace the bulb and the fast blinking will stop.

mporteous, It sounds like you have a light switch problem. I can't think of any other reason for the running lights and tail lights not working in this situation. Are your brake lights working when the headlights are off and how about when they are on? Do your four ways hazard lights work in these situations? Try all the lights under these conditions. The reason the left turn signal blinks very fast is because one of the bulbs are burned out. Try the left signal and one light (front or back) will stay on and the other will not come on at all. Replace the bulb that does nothing. Do this before you try all the lights in different situations. I think that you will have to replace the light switch. Good luck with this.

make sure our lights at rear are grounded sounds like a bad earth

the rapid blink is because there is a bulb outage some where, Pull Over turn on left Blinker Get out of your car look at the front left blinker hen walk to the rear of your car and look at the left rear Blinker light then do the same for the right side blinkers if all are working rapidly your left right switch is bad

You need to check your left side turn/park lamp bulbs for correct part # & installation.If that checks out you deffinetely have a ground problem.When you have other lights blinking with you turn signals you have either a bulb incorrect or a bad/poor ground.If bulbs check out check your forward lamp harness ground.Hope this helps

Usually a fast turn signal means that there is a light out. You should probably check all of your lights, including back-up lights, and turn signals. If there is one out then replacing the burnt out bulb should fix the problem.

sounds like a bad ground through one of your lights, the right front or rear turn signal bulb.

The problem could be the wiring connecting to the lights, you need to check them for bare wires. Look them through for any metal hanging out of the rubber insulation. You may need to get new wiring.

I have the same problem. I had it when I turned on my Blinker and turned. When the switch in the steering wheel turn the blinker off it made my head lights blink sometimes. It has to do with the switch that controls the blinker and the head lights. It does not happen all the time.
